9 Claims.

'This'invention relates to brackets and to the method ofmanufacturing said brackets.

It is an object of this invention to provide brackets formed from rolled metallic members which shall be stronger, less expensive, of equal adaptability and of about the same weight as brackets not formed of rolled members.

A further object is to provide brackets capable of being formed from structural sections.

A furtherobject is to provide a novel and economical method of producing brackets from structual sections.

Aiurther object is to provide brackets capable of being formed from standard rolled structurals wherein rivets utilized to secure the bracket elements together and the brackets to their associated members are subjected to shearing stresses and not tension stresses.

Other objects of the invention will become :clear as the description thereof proceeds.

In the drawings forming part of this specification:

Figure l is an end elevation of a structural section from which brackets embodying the in- :vention are produced and shows in dot and dash lines cuts made in the section to secure the several members of the bracket.

Figure 2 is a side elevation of the structural section of Figure 1. 1 Figure 3 is an elevation of one of the bracket members.

Figures 4 and 5 are plan views of the remaining members of the bracket.

Figure 6 is an elevation of the members of Figures 4 and 5. I

Figure '7 is a perspective view of the member of Figure 3.

Figure 8 is a perspective view of the members of Figures 4 and 5.

1; Figure 9 is a partial vertical elevation showing one application of the bracket.

Figure 10 is an elevation of the structure shown in Figure 9.

Referring to Figures 1 to 8 inclusive of the drawings which illustrate the bracket and process of manufacturing said bracket, the numeral Hi designates a section of a structural H-beam from which the elements of the bracket are produced. The H-beam I comprises a web ii and flanges l2 and It. In Figure 2 of the drawings, the H-beam is illustrated in side elevation and shows more clearly the cut lines made in the H-beam in order to yield the elements of the I bracket. The web I I of the H-beam may be out ;,along the dot and dash line aim in order to produce the element 14. This element may additionally be out along the dot and dash line dej for a purpose which will hereinafter apin section and comprises the stem l and the oppositely extending flanges l6 and H disposed at right angles to the stem.

The Web H is also out along the dot and dash line yhkmno thereby producing the section l8 from which the two elements l9l9 of the bracket are formed. In the preferred method of carrying out the invention the web II is cut simultaneously along the lines abc and "ghkmno in order to provide the element l4 and the section l8.

It will be apparent from a consideration of the section l8 and the bracket elements l9l9 which are preferably identical that the bracket elements are included in the section I8 and in said section are connected by a portion of the flange l3 of the H-beam section Ill. To secure the bracket elements iii-49 the section I8 is preferably disposed with the outside of the flange I3 uppermost. In this position the section I8 is out along the dot and dash lines pqr, stuv and xyz, these cuts preferably being made simultaneously.

The bracket element I9 is illustrated in greater detail in perspective in Figure 8 of the drawings.

This element embodies a stem 20 and oppositely extending flanges 2i and 22. It will be apparent from this figure of the drawings that the flange 2! is narrower than the stem 20 and is so disposed relative to the stem that shoulders 23 and 24 are provided. The length of each flange 2| and 22 which are at right angles to the stem by means of rivets which pass through the aligned openings 26 formed in the flanges 22-22 and 2'! formed in the stem l5. of the elements l9i9 is such that their narrower flanges 2I-2l extend upwardly above the The disposition stem [5 of the element l4. Moreover, the shoulders- 23 and 24 of each of the elements I9 are arranged flush with the upper edge of the stem l5. Also the stems 20-40 of the elements l9-l9 web 33 of the post 32.

extend horizontally in opposite directions from the stem 5. The arrangement of the elements I4 and i9l9 to provide the brackets is more clearly illustrated in Figures 9 and 10 of the drawings which in addition show one practical application of the novel bracket.

Referring to Figures 9 and 10 of the drawings, the numeral 38 indicates a side sill of a railway house car arranged with its web 29 vertical and its upper and lower flanges 3039 extending inwardly toward the center of the car. An intermediate post of the car side wall 31 is shown at 32 and as illustrated is formed of a. member which is Z-shaped in section and which comprises a web 33 at right angles to the wall, and inner and outer flanges 34 and 35. Metallic sheets 3636 are overlapped upon and secured to the outer flange by means of rivets 31'.

The inner flange 34 preferably terminates above the outer flange 35 as indicated at 38. The outer flange 35 is ofiset inwardly as indicated at 39 in order to accommodate the upstanding flange 46 of a bottom 2 connecting member 4!, the web 42 of which extends inwardly so that the inner depending flange 43 of said member may be riveted to the web 29 of the channel shaped side sill 28 as by rivets 44. The metallic sheathing 36-36 is secured by means of rivets 45 along its lower margin to the upstanding flange 40 of the bottom connecting 2 member 4|.

Applicants novel bracket 25 is employed in the above described car construction in order to provide a direct connection between the intermediate post 32 and the side sill 28. In this application of the bracket the flanges It and I! of the bracket element I l constitute attaching flanges by means of which the bracket is fastened to the web of the side sill by the rivets 44 and rivets 4B. The upper edge of the stem 15 and the stems 2020 of the bracket elements I9i9 underlie the web 42 of the bottom connecting 2 member 4! so as to provide a support for said member. The portion of the web I! and flange I2 of the H-beam removed by cutting along the dot and dash line def prevents interference between the bracket member l4 and the re-entrant angle formed by the web 42 and the depending flange 43 of the bottom connecting 2 member 4 i. It is to be understood that the recess provided by the removal of this portion of the H-beam is not limited either in size or contour to that shown in Figure 9 of the drawings. Any contour or size of recess which will avoid the interference above referred to is suflicient.

Stems 26-43 may be fastened to the web 42 by means of rivets 41. The flanges 2l2| of the bracket elements |8-l9 are utilized to provide attachments between the bracket and the To this end the web 42 of the bottom connecting Z 4! is coped as indicated at 43 so that the flanges 2l2l may extend upwardly through the bottom connecting Z and receive between them the web of the post 32. Securement between the flanges 2I-2| and the web 32 of the post may be obtained by means of rivets 49. It is to be observed that the upper edge of the stem !5 of the bracket element [4 together with the stems 2020 of the bracket elements 19-13 effectively seal the cope 48 provided in the web 42 so as to prevent the ingress of weather into the interior of the car and grain leakage. It is to be understood that the above described application of the bracket 25 is merely exemplary and that the invention is not to be limited to the use of the brackets in the particular structure illustrated.

It will be observed, moreover, that the construction of the bracket is such that the rivets utilized for the attachment of the bracket to the post and to the side sill as well as the rivets employed in the assembly of the bracket elements are subjected to shearing stresses and not tension stresses.

It will be apparent that numerous changes and modifications in the details of the invention will be clear to those skilled in the art. It is intended, therefore, that all such modifications and changes be comprehended within this invention which is to be limited only by the scope of the claims appended hereto.
